Maltsev conditions for general congruence meet-semidistributive algebras
arXiv:1810.03178 · doi:10.1017/jsl.2021.14
Abstract
Meet semidistributive varieties are in a sense the last of the most important classes in universal algebra for which it is unknown whether it can be characterized by a strong Maltsev condition. We present a new, relatively simple Maltsev condition characterizing the meet-semidistributive varieties, and provide a candidate for a strong Maltsev condition.
